Thread carrying cone



March 7, 1939. y J. H, GRITMAN 2,149,766 y THREAD CARRYING GONE Filed June l5,A 1938 In ventor Patented Mar. 7, 1939 UNITEDl STATES AT T 3 Claims.

My invention relates to improvements in thread carrying cones for use in supporting a load of thread wound thereon for weaving or knitting.

As will be understood in the art, in the weaving or knitting of fabrics, particularly silk fabrics, the best results are attained with the use of thread having a certain amount of moisture therein.

Having the foregoing in mind, it is the particular purpose of my invention to provide a practical, eflicient thread carrying cone adapted for the winding thereon of a large package of thread and equipped with means for supplying moisture to the thread in the proper degree.

Another object is 4to provide a thread carrying cone equipped for the purposes above set forth and also adapted for positively preventing sliding of thread wound thereon.

To the accomplishment of the above, and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawing, set forth in detail in the succeeding description, and defined in the claims appended hereto.

In said drawing:

Figure 1 is a view in longitudinal central section of a thread carrying cone constructed in accordance with my invention,

Figure 2 is a view in side elevation, partly in section, of the cone supporting spindle, and

Figure 3 is a View in side elevation of the inner shell.

Describing now my invention in detail, with reference to the drawing by numerals, the cone of my invention comprises as its basic feature an outer shell I of tubular form and suitable metal for receiving the thread and having lateral external and internal upper end flanges 2 and 3, and similar lower end flanges 4 and 5, the internal flange 5 forming an upwardly tapered bore 6 for a purpose presently seen. The shell I is stepped to provide sections l decreasing in size successively toward the upper end of the shell and separated by radial shoulders 8. The wall of the shell is perforated throughout its length, as at 9, to admit moisture from the interior of the shell to thread wound thereon, and each section 1 tapers downwardly so that thread wound on the shell packs downwardly against the shoulders 8, or the fiange i as the case may be, said shoulders and flange preventing the thread from slipping downwardly and the taper of the sections preventing the thread from slipping upwardly.

The shell I is designed to be supported, during the winding operation, as is usual, on a mandrel Iii including a shank II for insertion into said shell, having reduced ends I2 for rotatably mounting the mandrel in the usual bearings, not shown, a circular base I3 for supporting the lower end of the shell and having a boss I4 iitting into the bore 6 of said shell, a pulley I5 below said base for rotating the mandrel, and a collar I6 on the' upper reduced end I2 fitting in the flange 3 of the shell I to center said shell and mandrel with respect to each other.

As an adjunctive part of the device, there is provided a moistening unit having the form of a tubular perforated inner shell II adapted to be inserted in the outer shell I and comprising a lower end circular base I8` fitting against the lower end of the shell I, a circular boss I9 on said base I8 frictionally fitting into the bore 6, and an upper end similarly tting into the internal ange 3 at the upper end of the shell I. The inner shell II is of the p-roper diameter to clear the inner wall of the outer shell I and is preferably tapered upwardly to retain therein a sponge 2|. The sponge 2l is adapted to be saturated with water and the base I8 is provided with a small aperture 22 therein for drainage from said sponge.

As will be understood, the described moistening device is used only when the shell I is not mounted on the mandrel I I, or, in other words, when said shell is not used in throwing, and the thread is moistened by absorption from the sponge 2| through the shell I'I and shell I.

My invention will, it is believed, be clearly understood from the foregoing without further explanation.

Manifestly, the invention as described, is susceptible of modification without departing from the inventive concept and right is herein reserved to such modifications as fall within the scope of the subjoined claims.

What I claim is:-

1. A device of the class described comprising a tubular shell having upper and lower laterally and externally flanged ends and being stepped to provide sections decreasing in size successively toward the upper end of the shell and shoulders between said sections, each section being downwardly tapered.

2. A device of the class described comprising a tubular perforated shell having upper and lower laterally and externally flanged ends and being stepped to provide sections decreasing in size successively toward the upper end of the shell and shoulders between said sections, each section being downwardly tapered.

3. A device of the class described comprising a tubular perforated shell having upper and lower laterally and externally flanged ends and being stepped to provide sections decreasing in size successively toward the upper end of the shell and shoulders between said sections, each section being downwardly tapered, and an inner tubular perforated shell frictionally fitting at its opposite ends into corresponding ends of the first-mentioned shell and spaced from thelatter intermediate said ends.
